But if I use the original coil pos connection to supply key start/on voltage signal it's using the ballast resistor .

Running it thru the ballast resistor and I tend to think this is abad idea , correct ?
UNLESS I run a solid wire to bypass it on the backside of the ballast.

It is a MSD dist btw, combined with an MSD blaster 2 coil.

And yes, all the cars body wiring is still stock. One of my goals here is to be able to return it back to stock with minimul effort should the desire to arise sometime in the future.
